SHUTTLE-GUARD FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 630,263, dated August 1, 1899. Application filed April 13, 1899. Serial No. 712,865. (No model.)

To all whom it may concern.-

Be it known that I, JOSHUA B. NEWEL of Georgiaville, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Shuttle- Guards for Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the shuttle-guards attached to the lathe in looms to prevent the shuttle from being thrown from the raceway from any cause when the loom is running fast.

The object is to make the attachment of the guard to the cap-bar of the lathe simple in construction and easy to adjust with accuracy to accommodate the shuttle.

Figure 1 is a perspective View of a portion of the raceway and the cap-bar with the guard attached and a shuttle passing through back of the guard. Fig. 2 shows a vertical crosssection of the parts seen in Fig. 1, taken through one of the set-screws of that figure. Fig. 3 represents one of the hollow set-screws separate.

The construction of the guard is as follows:

N is the raceway of the loom-lathe. I B is the cap-bar, and J the reed held between B and N.

The guard consists of a small bar A, having a straight horizontal length that may be about one-half or so of the width of the cloth woven in the loom. At each end of this front length the bar is bent directly up a short distance and then back horizontally at right angles to the front length. The length of these back extensions should be sufficient to reach through the cap-bar when the front bar is far enough from the cap-bar to allow the shuttle to pass between them, as in Fig.1. A comparatively fine right-hand screw-thread-say twenty to the inch-is made for a short distance from the end on each of the back extensions, and two set-screws O O are made with holes through their centers lengthwise,

. and screw-threads are made in the holes to fit show outside of the set-screws. This is to prevent the guard from breakin golf if the weaver inadvertently catches hold of the guard to move the lathe, as it is very liable to break at the end of the set-screw if the thread err-- tends to or outside of the set-screw.

The guard is attached to the cap-bar by first screwing the nuts on the ends a of the bar a turn or so and then screwing the setscrews into the holes in the bar until the front bar of the guard is at the right distance from the reed for the shuttle to pass freely. This makes an inexpensive guard easily applied to anyloom, that can be easily adjusted, and that will not be changed by the incessant beating up of the lathe.

Having thus described my improvement, I

claim as my invention and desire to secure by Letters Patent- A shuttle-guard for looms, consisting of a bar or rod having a straight front horizontal portion, and bent up at each end a short distance, and then bent off horizontally at right angles to said front portion,and having a comparatively fine screw-thread made on the ends, in combination with two hollow setscrews having a coarse screw-thread made on them, and screw-threads made in them fitting on the threaded ends of the rod, said screw-threads being bored out of the head end of the set-screws, and a cap-bar having holes made in it to receive said set-screws, substantially as described.

In testimony whereof I have hereunto set JOSHUA B. NEWELL.

In presence of- BENJ. ARNOLD, E. B. READ.

my hand this 12th day of April, A. D. 1899.
